Wi ow of William HWZlerts, @memset site clement is adapted engaged by the hook.

of separate cars are uncoupled, the connection between the head and L-extension Will 'be disrupted. Each coupling element is providedl with the central aperture and substantially circular body 29 which is connected to the headQG by a spiral spring 30 so that the elements 2S are normally raised against a. stop 30a, so as to throw the apertures in the head 2G and the L -eXtensionlQ out of register. `"lach element has a return hoolr formed thereon, shown at 31, and provided with an arcuate shoulder against which the oppot-o'abut. The underneath side of the hook is provided with a cam surface 33 over which an arcuate pro-- jection 34; is adapted to wipe. Each element is provided with one of these projections which is adapted to engage the cam surface of the opposite hook and each element is also provided with a stop in the form of a rod 35 which extends over the body of the element across the intervening space to be Each element as they approach each other abuts the arcuate shoulder upon the hook of the opposite element .and as their bodies turny upon the shoulders and the L-extensionsturn in the heads 26, the elements 28 are depressed tothe position shown in Fig. 1the arcuatev projections 34 wipe upon the cam surfaces 33, draw the elements together with their central apertures registering. As the elements 28y are de# pressed the apertures in the L-extension and the heads 2S are brought into register so that the cars have their steam, air, and sig-I nal systems connected. l f l In order to guide thecoupling elements of the separate cars into engagement with each other and the framesv Q into engagement, the frames are provided with a plurality of alternately arranged short and long fingers 3G and 37, respectively which have their outer ends inwardly and outwardly turned in order of their numbers and which coperate the' similar ingers on opposite sides of the opposite frame. For instance, the short lingers '8G of the lcit hand frame coperate with the long fingers 37 lon the opposite rame,vvhile the long nger 37 which lies in the` same plane withthe short finger 36 co- 50 operates with a short finger on the opposite rame,as shown. Projecting laterally -from the frames) of the opposite cars are stop membersdand 39 which abut each other When'theframesare brought together and 55 the nger's are in engagement so as to relieve the strain uponthe pins 35.

What is claimed is Y l. In a mechanism of the class described, the combination with mounting evices 60 adapted to be secured upon the o posite cars to be connected, frames connected to. said mounting devices for vertical and lateral movement, means for holding the frames normally in coupling position, a plurality of train pipes secured to the frames, coupling elements carried by the frames and having a valved and pivoted connection with said pipes and means to interengage the elements andthe frames of the separate '70' "i cars. i

2. Ina mechanism of the class described;- the combination with supporting devices, frames slidably 'mounted on and connected to the supporting devices, for verticaland lateral movement, means for holding the frames resiliently separated from the supporting devices, a plurality of coupler elements carried by the frames, a plurality of train pipes secured to the mounting devices, valved and pivoted connections between the pipes and-the coupler elements, means to inter-engage the frames of the separate cars, means to connect the coupler elements of the separate cars engaged, and means to operate the coupler elements toclose thevalves when the frames are disconnected. In testimony whereof, 'I-aiiiX' my signature in the presence ,of two witnesses.
